Knowledge of the imaging anatomy of the wrist is essential for reporting magnetic resonance imaging (MRI). This familiarity should include the carpal bones, tendons (extensor and flexor compartments), triangular fibrocartilage complex (TFCC), intrinsic and extrinsic ligaments, and nerves, especially the median and ulnar nerves. Limitations of MRI in visualizing these structures, particularly the intrinsic ligaments and the TFCC, need to be considered.

Background: To evaluate the accuracy of ultrasound (US) in diagnosing the the presence and type of groin hernia.
Methods: We retrospectively studied the results of 172 US examinations of the groin in 151 patients (101 men and 50 women; mean age, 59 years) who had undergone US examination for suspected groin hernia. In total, 119 of the groin hernias had been diagnosed on US, and 108 (91%) had required subsequent surgery.
The anterior cruciate ligament (ACL) is an important structure in maintaining the normal biomechanics of the knee and is the most commonly injured knee ligament. However, the oblique course of the ACL within the intercondylar fossa limits the visualization and assessment of the pathology of the ligament. This pictorial essay provides a comprehensive and illustrative review of the anatomy and biomechanics as well as updated information on different modalities of radiological investigation of ACL, particularly magnetic resonance imaging.
